Install CentOS6.5 on a USB disk

I'll just talk about CentOS installation as a server, but for the general CentOS installation process, first download the CentOS installation image file, there are several: CentOS-6.5-x86_64-LiveCD, CentOS-6.5-x86_64-LiveDVD, CentOS-6.5-x86_64-bin-DVD1, CentOS-6.5-x86_6

I only want to talk about CentOS installation as a server, but it is applicable to the general CentOS installation process. first, download the CentOS installation image file, which has the following types: centOS-6.5-x86_64-LiveCD, CentOS-6.5-x86_64-LiveDVD, CentOS-6.5-x86_64-bin-DVD1, CentOS-6.5-x86_64-bin-DVD2, CentOS-6.5-x84_64-minimal.

The CentOS-6.5-x86_64-bin contains all the optional software, as I only use CentOS as the server, so just download minimal and select the corresponding version as needed. After downloading, you can burn iso to CD/DVD for installation. because there is usually no optical drive on the server, to facilitate usb installation, you must first write iso to the usb hard drive image, in windows, you can select UltraISO and other software, but I always have problems starting after writing. I chose to use the dd command in Ubuntu to write usb (# sudodd if =/home/CentOS. iso of =/dev/sdb. if you don't know which device your USB flash drive is, you can use # sudo fdisk-l to view it ), then you must set the hard disk to AHCI mode in the bios. Otherwise, the usb installation may not be detected during startup.

If your machine has already installed CentOS, it will enter the CentOS installation selection interface:

Install or update an existing system Install or upgrade the existing system

Install system with basic video driver

Rescue installed system enters system repair mode

Boot from local drive exit installation start from hard disk

Memory test Memory detection

The next step is to install the tool. if there is any prompt before entering the boot interface, skip or always OK. next, the language does not matter (here is only the prompt language of the boot interface, if LiveCD or LiveDVD is installed, the keyboard layout U. s. select BasicStorageDevices (basic storage device), Hostname server name (localname. localdomain), network installation is complete in the configuration, time zone, then set the root password (remember ).

Note that hard disk partitions are used as servers, so we choose to Use AllSpace. if you want to Use dual systems or other options, you can refer to other options for setting, select Peview and modifypartitioning layout, next, write changes todisk, and next. for LiveCD and DVD, select Minimal and wait until installation is complete.
